sleep with us and they wake with us.

If, however, we learn better habits of sleeping, that helps us in
our life through the day. And learning better habits through the day
helps us to get more rest from our sleep. At the end of a good day
we can settle down more quickly to get ready for sleep, and, when we
wake in the morning, find ourselves more ready to begin the day to
come.

There are three things that prevent sleep,--overfatigue, material
disturbances from the outside, and mental disturbances from, within.

It is not uncommon to hear people say, "I was too tired to sleep"
--but it is not generally known how great a help it is at such times
not to try to sleep, but to go to work deliberately to get I rested
in preparation for it. In nine cases out of ten it is the
unwillingness to lie awake that keeps us awake. We wonder why we do
not sleep. We toss and turn and wish we could sleep. We fret, and
fume, and worry, because we do not sleep. We think of all we have to
do on the following day, and are oppressed with the thought that we
cannot do it if we do not sleep. First, we try one experiment to see
if it will not make us sleep, and when it fails, we try another, and
perhaps another. In each experiment we, are watching to see if it
will work. There are many things to do, any one of which might help
us to sleep, but the _watching to see if they will work keeps us
awake._

When we are kept awake from our fatigue, the first thing to do is to
say over and over to ourselves that we do not care whether we sleep
or not, in order to imbue ourselves with a healthy indifference
